SEWING MACHINE Application sied March e1, lesa. serial N. 602,357.

This invention relates to sewing machines and has special reference to a button sewing attachment for sewing machines particularly adapted to sewing buttons having leather 5 Shanks ontoV articles of clothing.

I @ne important object of the invention is to provide an'improved general construction of device for this purpose.

A second important object of the invention l is to provide an improved means, in such a device, for properly holding the button to present the shank of the button in position for sewing.

A third important object of the invention l is to provide means for holding the so-called stay button in place.

A fourth important object of the invention is to provide novel means for releasing the button holding means of the device.

lVith the above and other objects in view, as will presently be explained, the invention consists in general of certain novel details of construction and combinations of parts, hereinafter fully described, illustrated in the accompanying drawing, and

claimed.

In the accompanying drawing the characl ters of reference indicate like parts in the several views, and

Figure 1 is a side elevation of the invention with certain parts of a sewing machine shown in broken lines in relation thereto.

Figure 2 is a plan view of the invention.

Figure 3 is an enlarged detail, on the line 3 3 of Figure 1, and showing the means for holding the stay button.

Figure 4 is an enlarged detail the line 4 4 of Figure 2.

Figure 5 is an enlarged detail section on the line 5 5 of Figure 4.

In the present embodiment of the invention there is provided a bracket 10 of Z-shape section, on

and which has its lower Hangs suitably sup-` ported to reciprocate on the bed (not shown) use. On the upper flange of the bracket rests one end 11 of a button carrier supporting bar which is provided with longitudinally extending slots 12. Through one of these slots extends a clamp screw 13 and in the other notches 20 to receive the shank speciically of the machine when the attachment is iny slot is received a guide pin 14. By this means the supporting bar may be adjusted on the bracket 10.' The free end of the supporting.V bar isinclined downwardly, vas at 15, and to ,the lower part of this end is secured Vtheta upwardly inclined shank portion 16 of a button shank holder having a horizontal bod portion 17. Thebody 17 is provided, with a vertical needle opening 18 at about its center and leadingrom this opening is a. slot 19.69 which opens through the, free edge of the body andY is provided with horizontal opposed S of a button B.v The opening and slot thus form a keyhole slot havingopposed notches in the walls of its ,65 stem portion. Mounted on top of the body 17 is a guard plate 21 having slots 22 through which pass securing screws 23. This plate has an uplurned edge portion 24 extending over thej free edge of the body17 to protect and support the button .against tilting. A second guard or wear plate 25 is secured beneath the "body 17 and both of p theseguard plates are slotted with keyhole slots similar to the body. At 26 is a bracket in the form ofa vertical plate and which is provided with a foot 27 resting on the bar portion 15 and secured thereto by suitable screws. The bracket 26 is spaced from the side of the bar 15. The 3o free end of this bracket lies behind the needle bar N of the machine and to thisfree end is pivoted one end of a clamp member 28 having a forwardly extending arm 29 provided 'with a button holding finger 30 arranged to.85 press normally against the top of the button" B andi hold it inv position. In the clamp member is formed a cam slot 31 wherein works a cam pin 82 carried by one end of a release lever 33 which is pivoted intermediate its@ ends to the Abracket 26, asiat 34. The other end of this lever is provided with a foot 35 which extends beneath the bar portion 11.

Extending upwardly from this :toot is a pin 36 which passes through a suitable opening in. the har 11 and is provided on its upper end p with a head 87. Aspring 38 surrounds the pin between the head 37 rand the bar 11l and urges this end'of the lever upwardly and the y opposite end downwardly so as to force the f m0 finger against the button B. Obviously, downward pressure on the head 37 will release the button.

Below the bracket 10 is an operating arm 39 to which is fixed a blade or extension 40 which terminates in alinement with the free edge vof the body 17. Mounted on the free end of this blade is a plate 4l which has screw and slot connection with the blade to permit adjustment of the plate longitudinally ofithe blade. On this plate beneath the body 1'7 is fixed a stay button holder 42 having 1a suitable pocket 43 for a stay button b and slotted similarly to the body 17 Overlying a 'portion ofthe ,pocket 43` is a spring clamp 44 which is'connected to the blade40 by a screw yfand slot connectionf45 `so that the clamp 44 may be suitably adjustedwith relation to the 'button pocket 43. 2o

Fired to the barportion 15 isa rearwardly extendingbracket 46 which carries at its rea-r end a post 47 suitably connected to the presser foot bar (not shown) of the'inachine,"as by the arm 48 and chain 49. y n

As is common in'button vsewing machines, the bracket 10 and bar 39 are'reciprocated by suitable mechanism to enable the needle N to fio y fsh'ank receiving Ipass through the loop of the button shank on r one lreciprocation and outside 'such loop on the second reciprocation, thus passing through the openings of the stay button alternately. This reciprocating means forms H'no'part of the invention and consequently is not here shown.` n p Alnoperation, the head 37 is pushed down andthe finger I3() raised. The button B is n ow positioned as shown in Figures l kand 4 ,and the finger released. Also'the button b I is placed in position. v'Ihefaybricis now in- V serted between the body 17 and member '42 Aandthe sewing operation carried out. When Vthis is finished the finger 30 isagain released andthe button removed.V Y A Y There has thus been provided asimple Aand eficient device of the kind 'describedand for the purpose specied. p l

It is obvious that changes may be made inthe form and construction of the` invention without departing from the principles involved. It snot, therefore, desired to coninvoice opposite the open end of said slot, and spring means urging the finger toward the body.

2. In a device ofthe kind described, a button holding member including a body having a keyhole needle slot therein opening through the free edge of the body and having itsside wallsy provided with opposed button shank receiving grooves at the open end, a supporting bar carrying said body, a bracket carried by' said bar, a presser arm pivoted to said bracket and having a finger positioned opposite the open end of said slot, a lever pivoted intermediate its ends to said bracket, a

lpin and slot connection between one end of said i said lever and said arm whereby to move arm onits pivot as the lever is rocked, and spring means urging said lever to move the finger toward said body.

'3. In a device ofthe kind described, aV stay button holder including a blade, a bodyy having a button recess therein, means to securey said bod 'for adjustment on said blade, a

button holding spring having one end overlapping'said recess',raiid means to secure said spring adgustably along said blade.

In testimony whereof, I aiiiX my signature.
